Mouth ulcers concerns

Mouth ulcers are painful sores that appear in the mouth, usually on the soft tissue - cheeks, lips or tongue. They can be white, red, yellow or grey in colour and swollen.

Although they're uncomfortable, mouth ulcers are usually harmless and clear up by themselves within a week or two.

In many cases, the reason for mouth ulcers is unclear, but triggers are thought to include:

  • Accidentally biting the inside of your cheek or a sharp tooth
  • Poorly fitting dentures
  • Hard food
  • A defective filling
  • Stress and anxiety
  • Hormonal changes – some women develop mouth ulcers during their monthly period
  • Eating certain foods – such as chocolate, spicy foods, coffee, peanuts, almonds, strawberries, cheese, tomatoes and wheat flour
  • Toothpaste containing sodium lauryl sulphate
  • Stopping smoking – when you first stop smoking, you may develop mouth ulcers
  • Viral infections – including the cold sore virus, chickenpox, and hand, foot and mouth disease
  • Medical conditions - including vitamin B12 or iron deficiency, Crohn's disease, coeliac disease, reactive arthritis, HIV, lupus, Behçet’s disease
  • Certain medications or medical treatments may also cause mouth ulcers

It's usually safe to treat mouth ulcers at home to help reduce swelling and ease any discomfort.

Self care

Tips for easing discomfort and aid healin…

  • Antimicrobial mouthwash or protective paste, available from your pharmacist
  • Use a soft toothbrush to brush your teeth
  • Use a toothpaste that doesn’t contain sodium lauryl sulphate, as this may be irritating
  • Avoid hard, spicy, salty, acidic or hot food and drink until the ulcer heals
  • Use a straw to drink cool drinks
  • Avoid things that may be triggering your mouth ulcers

Mouth ulcers can sometimes be a possible symptom of a more serious problem such as infection or mouth cancer. It's therefore essential that you contact [practice name] as soon as possible if you notice:

  • your mouth ulcer has lasted three or more weeks
  • you keep getting mouth ulcers
  • your mouth ulcer becomes more painful or red

Marc Mortiboys is my and my husband dentist since the beginning of the his practice. I fully trust him with my teeth. Just wanted to add that the whole place is in need of some decorating, it’s looking very unkempt especially in the reception area

I recently returned to Mortiboys Dental Spa for a checkup after being away for quite a few years, and I couldn’t be more pleased with how everything went. Having not seen a dentist for at least 4–5 years, I was a little unsure what to expect, but the team treated me with genuine respect from the moment I arrived.The atmosphere was friendly yet thoroughly professional, and I felt completely at ease throughout my visit. The checkup was carried out with care, reassurance, and clear explanations, which made the whole experience far better than I anticipated after such a long gap.A big thank you to the team for making my return to the dentist such a positive one.

All aspects of treatment, communication with all staff is excellent. Used to hate dentist visits now no problem!

I am treated as a person not just a patient. I am listened to and accommodated. Very thorough treatment - always. Dentist and Hygienist trauma has abated since coming to this practise. Thank You!

Friendly professional service as always.

If I was highly satisfied, and all of my answers confirm this, why do I need to add further comment. I had an emergency consultation which was highly satisfactory with a number of treatment options. What more could I add? Stupid added survey question!

25th July 2026

Things explained very well. Can't fault the system or the staff.

24th July 2026

I was fully consulted and listen too - plus treatments option were fully explained by a caring and pleasant team.
